Title: Two-compartment aerosol container
Inventor: LILIENTHAL JOHANNES HEINRICH
IPC: B65D83/14
Filed: 1984-05-14
Granted: 1987-08-20
Abstract: A double-chamber aerosol container is constructed using two conventional aerosol receptacles each having a valve at one end. A first of the receptacles is an outer receptacle which contains one of the components of the product to be dispensed. The other of the receptacles is smaller and is contained within the outer receptacle with its valve facing the bottom of the outer receptacle. The inner receptacle contains a propellent gas and a second component of the product to be dispensed. The outer container has an inwardly displaceable closing plug in its bottom which, when displaced inwardly opens the valve in the inner receptacle to discharge the contents of the inner receptacle into the outer receptacle. A sealing gasket surrounding the closing plug permits it to be displaced inwardly while maintaining the sealed condition of the container.

Abstract: The present invention relates to a method and apparatus for treating fiber suspension. The method and apparatus in accordance with the present invention is especially suitable for treating the fiber suspensions of the wood processing industry, for example, in thickening or washing pulp. The methods and apparatuses in accordance with prior art techniques have recently been based on using vacuum filters. In other words, the separation of liquid from the pulp has been based on the fact that an underpressure has been arranged on one side of the pulp cake, whereby the external atmospheric pressure has displaced liquid in the pulp. Thereby air has passed into the pulp causing slime problems among other things. On the other hand, a drawback with such apparatus has been their poor ability to utilize the filter surface, because only 50 - 60 % of the total filter surface area has even under the best conditions being efficiently used. The method and apparatus in accordance with the present invention enables the use of almost the whole filter surface by arranging the pressurized feed of the pulp to the apparatus, whereby liquid is separated due the lower pressure, for example the normal atmospheric pressure prevailing behind the filter surface. On the other hand, the discharge of the pulp cake has been arranged to be carried out from only a very limited portion of the filter surface, whereby the use of the filter surface area is even further intensified.
